Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment one:A kind of cement mixing pile building enclosure, as shown in Figure 1, including cement mixing pile 1, cement mixing pile 1 Interior be equipped with reinforces building enclosure 2, and reinforcing building enclosure 2 includes some reinforcing bars 21 being fixedly connected and reinforcing bar 21 is fixed and connected The protection network 22 connect, after the stirring work of cement and weak soil is completed, before cement mixing pile 1 is molded, knot is gone along with sb. to guard him by reinforcing Structure 2 is placed into not solidified cement mixing pile 1, and the bending resistance of cement mixing pile 1 is improved by reinforcing bar 21 and protection network 22 Performance and shear resistance.
As shown in Figure 1, reinforcing bar 21 is made by iron with protection network 22, iron has certain strength and stiffness, is conducive to add Gu the stability of building enclosure 2, so as to improve the anti-bending strength and shear resistance of cement mixing pile 1, while itself also has well Chemical property, improve service life.
As shown in Figure 1, reinforcing bar 21 include some transverse steels 211, it is some be fixedly connected with transverse steel 211 it is vertical Reinforcing bar 212, vertical reinforcement 212 surround the cylinder 4 of cylinder, gap are equipped between adjacent vertical reinforcement 212, in cylinder 4 Spacer bar 3 is equipped with center, 211 one end of transverse steel is fixedly connected with spacer bar 3, and the other end is solid with vertical reinforcement 212 Fixed connection, vertical reinforcement 212 and transverse steel 211 are joined together to form entirety, reduce single vertical bold move Situation, be conducive to entirely reinforce building enclosure 2 stabilization.Meanwhile the gap between adjacent vertical reinforcement 212 so that cylinder 4 When being under pressure, not solidified cement mixing pile 1 can flow in gap, reach reduce cylinder 4 be under pressure and Situation about being moved.
As illustrated in fig. 1 and 2, protection network 22 is arranged on the outside of cylinder 4, the part transverse steel 211 is to the outside of cylinder 4 Extend and be fixedly connected with protection network 22, protection network 22 is cylinder and is set in the outside of cylinder 4, and protection network 22 is to whole cylinder Comprehensive protection is realized in the outside of body 4, and the pressure in cement mixing pile 1 can be applied on protection network 22 first, protection network 22 The pressure of a part can be unloaded, reduces the situation that position movement occurs in building enclosure 2 of reinforcing.
As shown in figure 3, the transverse steel 211 in cylinder 4 is uniformly staggered along the axis of spacer bar 3, adjacent two The position that transverse steel 211 on vertical reinforcement 212 is set is not in same level height, so that cross bar is in spacer bar 3 Axially account for the space of bigger so that cement mixing pile 1(As shown in Figure 1)Interior transverse steel 211 is also evenly distributed as far as possible, subtracts It is small the low distribution of partial intensities high part intensity occur, be conducive to improve the anti-bending strength and shear resistance of cement mixing pile 1.
As shown in figure 3, in order to effectively improve the stability between spacer bar 3 and vertical reinforcement 212, connect every and erect It is more than or equal to three to the quantity of reinforcing bar 212 and the transverse steel 211 of spacer bar 3, vertical reinforcement 212 is logical with spacer bar 3 Excessive root transverse steel 211 connects, and is conducive to vertical reinforcement 212 and stablizes relative to the position of spacer bar 3, improves cylinder 4 Intensity so that improve reinforce building enclosure 2 stability.
As shown in figure 3, when vertical reinforcement 212 and transverse steel 211 are implanted in not solidified cement mixing pile 1, The weak soil of surrounding has certain pressure, the situation that vertical reinforcement 212 can be caused to move up.In transverse steel 211 and vertical reinforcement Hangnail 5 is equipped with 212, for vertical reinforcement 212 when there is situation about rising, hangnail 5 can produce certain resistance, so as to reach Reduce the situation that 212 stress of vertical reinforcement rises.
It is implanted into as shown in Figure 1, cement mixing pile 1 when non-coagulation forming, will reinforce building enclosure 2, due to not coagulating Solid cement mixing pile 1 also have certain resistance, the implantation that can stablize of building enclosure 2 is reinforced for convenience, in vertical reinforcement 212 are equipped with spine 6 close to one end of 1 bottom of cement mixing pile, and one end away from 1 bottom of cement mixing pile is equipped with bearing plate 7(Such as Shown in Fig. 3).
As shown in Figure 1, reinforcing building enclosure 2 when cement mixing pile 1 is injected, spine 6 facilitates reinforcing bar 21 and inserts Enter to the inside of cement mixing pile 1, while reinforce building enclosure 2 during insertion, it is necessary to which certain beats or compress Power, bearing plate 7(As shown in Figure 3)The forced area on vertical reinforcement 212 is improved, facilitates and is realized to reinforcing building enclosure 2 Beat or compress, reduce reinforcing building enclosure 2 and be subject to beat the situation that power is damaged, so as to be conducive to reinforcing going along with sb. to guard him knot The inside for being implanted to cement mixing pile 1 of 2 fast and stable of structure.
Embodiment two:A kind of cement mixing pile building enclosure, is with one difference of embodiment, as shown in figure 4, protection Net 22 is plane straight panel shape, and protection network 22 is equipped with six pieces and is staggered in hexahedron shape.The protection network 22 being staggered is to cylinder The effect that the surrounding of body 4 is also protected, since protection network 22 is not integral type, can produce deformation after stress, can unload Carry the pressure that a part is transmitted on cylinder 4, be under pressure so as to reduce and be transmitted on cylinder 4, reach the position for reducing cylinder 4 The purpose being moved is put, the positional stability for reinforcing building enclosure 2 in mixing pile is improved, is finally reached raising cement mixing Stake 1(As shown in Figure 1)Anti-bending strength and shear resistance.
Embodiment three:A kind of cement mixing pile building enclosure, is with one difference of embodiment, as shown in figure 5, protection Net 22 is arc-shaped, and protection network 22 is equipped with four pieces and is staggered cylindrical.The protection network 22 being staggered is to the four of cylinder 4 The effect that week is also protected, while a contact area of protection network 22 and mixing pile is also increased, improve reinforcing and go along with sb. to guard him knot Positional stability of the structure 2 in mixing pile.
As shown in figure 5, it is not a bodily form due to being staggered when protection network 22 is under pressure effect at the same time Into stress can produce deformation afterwards, can uninstall the pressure that a part is transmitted on cylinder 4, cylinder is transmitted to so as to reduce It is under pressure on body 4, the position for achieving the purpose that to reduce cylinder 4 is moved, and improves and reinforces building enclosure 2 in cement mixing pile Positional stability in 1, is finally reached the anti-bending strength and shear resistance for improving cement mixing pile 1.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but As long as all protected in the right of the utility model be subject to Patent Law.
